The specific embodiment

This new and effective accurate filter is made up of following respectively using: airtight container (11), piston (1), cylinder (2), threaded central tube (3), upper filament hanging tray (4), lower filament hanging tray (5), filament (14), card (9), exhaust outlet (21), compressed air are imported and exported compositions such as (16).Its characteristics are:

1, one or several filter core unit (22) is housed in the container of a sealing (11), the filter core unit by piston (1), cylinder (2), central tube (3), on hang parcel (4), hang parcel (5) down, filament (14) is formed.

2, when compressed air is entered in the cylinder (2) by air inlet/outlet (16-1) exhaust by air inlet/outlet (16-2), piston (1) begins to move upward, the big helical pitch external screw thread in big helical pitch nut Yanzhong core barrel (3) top on the piston (1) begins rotation and rises, drive the last filament of hanging (14) of upper filament hanging tray (4) and upper filament hanging tray (4) simultaneously and together do the rotation rising, make the filament lash on the central tube (3) of with holes and water strainer, form a fiber filtering layer that is tightened on the central tube (3), at this moment enter untreated water by water inlet (10), discharge by delivery port (13) after filtering, at this moment, the product water turbidity of discharge can reach 1-3mg/l.(see figure 1)

3, when compressed air by air inlet/outlet (16-1) the entrance pressure top of air of contracting to cylinder (2), by air inlet/outlet (16-2) exhaust, at this moment, piston (1) begins to move downward, the big helical pitch external screw thread rotation that the big helical pitch nut of piston (1) begins Yanzhong core barrel (3) top descends, make the filament of nut screwing clamping on central tube (3) loose to reset condition, at this moment can carry out backwash, backwash adopts gas+water to mix flushing, backwashing water is gentle to be entered by effluent pipe mouth (13), water after the flushing is discharged by water inlet (10), and air is discharged by exhaust outlet (21), finishes the process (see figure 2) of backwash.
